“…Therefore, bipolar systems are deemed to be safer than monopolar systems [16]. In spite of the advanced surgical instruments attached to ESUs that enable “vessel sealing properties” in laparoscopic surgery, conventional monopolar and bipolar systems are still popular [14, 16, 20]. The majority of laparoscopists still prefer conventional monopolar and bipolar surgical tools [21].…”

“…In a study comparing the thermal effects of the Stryker (Stryker Endoscopy, Kalamazoo, MI, USA) and ERBE Erbotom VIO 300 D ESUs on uterus using conventional instruments, the ERBE Erbotom VIO 300 D unit was associated with decreased depth of injury and lateral damage in the tissue [20]. In line with the literature, our results related to the ERBE Erbotom VIO 300 D unit showed less thermal injury depth and lateral damage with the monopolar system compared with the other 2 ESUs.…”

Background/Aims: The objective of this study was to compare the depth and width of thermal spread caused on rat uterine tissue after application of 3 different electrosurgical generators. Methods: Alsa Excell 350 MCDSe (Unit A), Meditom DT-400P (Unit M), and ERBE Erbotom VIO 300 D (Unit E) electrosurgical units (ESUs) were used. The number of Wistar Hannover rats required to obtain valid results was 10. The primary objective of the study was to compare the 3 ESUs using the same instrument and the same waveform. The secondary objective of the study was to compare the differences between monopolar and bipolar systems of each ESU separately using the same waveform. Results: The thermal spread caused by each ESU using monopolar instruments with continuous and interrupted waveforms was significantly different. Among the 3 devices, Unit A caused the largest thermal uterine tissue spread. On the other hand, Unit E caused the most superficial thermal tissue spread, and the smallest thermal spread among all ESUs. Conclusions: Surgeons should note that different ESUs used with the same power output might create different thermal effects especially in the monopolar configuration within the same waveform, for the same duration, and with the same instrument.

“…1,2 The tissue impacts produced with monopolar electrosurgery incorporate vaporization (tissue destruction and cutting), fulguration (tissue destruction and little vessel hemostasis), desiccation (cell wall break and cytoplasm boiling), and coaptation (vessel sealing inferable from denaturation and renaturation of proteins) ( Table 1). 2 These tissue impacts are fundamentally accomplished by using the "cut" or "coag" mode of electrosurgical unit (ESU) while contacting or non contacting the objective tissue (Table 2). 3 Varying other parameters are under the specialist's control, such as power setting, length of enactment, and terminal arrangement, can facilitate adjusting the wanted tissue effect.…”

“…3 Varying other parameters are under the specialist's control, such as power setting, length of enactment, and terminal arrangement, can facilitate adjusting the wanted tissue effect. [1][2][3] All energy sources generate tissue temperatures above 45°C, the temperature at which irreversible cell damage occurs. Monopolar electrosurgery generates tissue temperatures of ~100°C, 100-200°C, and >200°C for desiccation, vaporization, and fulguration respectively.…”

Introduction: There are devices that apply energy to cut, coagulate, and desiccate the tissue with minimal bleeding and by overcoming the hindrance of laparoscopy facilitate minimal access surgery. The inappropriate utilization of electrosurgical devices may expand horrible morbidity and mortality. The present article surveys different electrosurgical sources as far as their basic uses and safe practices.

“…This was later modified with bipolar graspers, that allowed the energy to be more focused, diminishing surrounding tissue damage. Latter ultrasonic instruments allowed sealing larger diameter blood vessels and diminished carbonization of the adjacent tissues with no vapor to obstruct visualization, and thanks to the integrated knife a central cut was obtained [1].…”

Use of the radiofrequency Caiman® Aesculap® Grasper in three different laparoscopic urologic procedures with video

Introduction: The Caiman grasper is a radiofrequency instrument that allows cutting and sealing of tissues and blood vessels, with the added benefit of a distal closure that allows a stable pressure in its 26.5mm long tip, with a less than 1mm thermic injury of the adjacent tissues, with energy regulation depending on the tissue characteristics, allowing to seal up to 7mm vessels. All the above makes dissection easier and diminishes surgical time, making the laparoscopic procedures safer and faster, including urologic surgeries.
